Description
FIELD
[0001] The present invention is related to a lighting apparatus,
and more particularly related to a lighting apparatus with
extending functions.
BACKGROUND
[0002] The time when the darkness is being lighten up by the light,
human have noticed the need of lighting up this planet. Light has
become one of the necessities we live with through the day and the
night. During the darkness after sunset, there is no natural light,
and human have been finding ways to light up the darkness with
artificial light. From a torch, candles to the light we have
nowadays, the use of light have been changed through decades and
the development of lighting continues on.
[0003] Early human found the control of fire which is a turning
point of the human history. Fire provides light to bright up the
darkness that have allowed human activities to continue into the
darker and colder hour of the hour after sunset. Fire gives human
beings the first form of light and heat to cook food, make tools,
have heat to live through cold winter and lighting to see in the
dark.
[0004] Lighting is now not to be limited just for providing the
light we need, but it is also for setting up the mood and
atmosphere being created for an area. Proper lighting for an area
needs a good combination of daylight conditions and artificial
lights. There are many ways to improve lighting in a better cost
and energy saving. LED lighting, a solid-state lamp that uses
light-emitting diodes as the source of light, is a solution when it
comes to energy-efficient lighting. LED lighting provides lower
cost, energy saving and longer life span.
[0005] The major use of the light emitting diodes is for
illumination. The light emitting diodes is recently used in light
bulb, light strip or light tube for a longer lifetime and a lower
energy consumption of the light. The light emitting diodes shows a
new type of illumination which brings more convenience to our
lives. Nowadays, light emitting diode light may be often seen in
the market with various forms and affordable prices.
[0006] After the invention of LEDs, the neon indicator and
incandescent lamps are gradually replaced. However, the cost of
initial commercial LEDs was extremely high, making them rare to be
applied for practical use. Also, LEDs only illuminated red light at
early stage. The brightness of the light only could be used as
indicator for it was too dark to illuminate an area. Unlike modern
LEDs which are bound in transparent plastic cases, LEDs in early
stage were packed in metal cases.
[0007] In 1878, Thomas Edison tried to make a usable light bulb
after experimenting different materials. In November 1879, Edison
filed a patent for an electric lamp with a carbon filament and keep
testing to find the perfect filament for his light bulb. The
highest melting point of any chemical element, tungsten, was known
by Edison to be an excellent material for light bulb filaments, but
the machinery needed to produce super-fine tungsten wire was not
available in the late 19th century. Tungsten is still the primary
material used in incandescent bulb filaments today.
[0008] Early candles were made in China in about 200 BC from whale
fat and rice paper wick. They were made from other materials
through time, like tallow, spermaceti, colza oil and beeswax until
the discovery of paraffin wax which made production of candles
cheap and affordable to everyone. Wick was also improved over time
that made from paper, cotton, hemp and flax with different times
and ways of burning. Although not a major light source now, candles
are still here as decorative items and a light source in emergency
situations. They are used for celebrations such as birthdays,
religious rituals, for making atmosphere and as a decor.
[0009] Illumination has been improved throughout the times. Even
now, the lighting device we used today are still being improved.
From the illumination of the sun to the time when human can control
fire for providing illumination which changed human history, we
have been improving the lighting source for a better efficiency and
sense. From the invention of candle, gas lamp, electric carbon arc
lamp, kerosene lamp, light bulb, fluorescent lamp to LED lamp, the
improvement of illumination shows the necessity of light in human
lives.
[0010] There are various types of lighting apparatuses. When cost
and light efficiency of LED have shown great effect compared with
traditional lighting devices, people look for even better light
output. It is important to recognize factors that can bring more
satisfaction and light quality and flexibility.
[0011] It is important to add flexibility to light devices. For
example, more functions may be added to existing light devices.
[0012] Furthermore, it is helpful if the functions can be changed.

DETAILED DESCRIPTION
[0066] In FIG. 9, a lighting apparatus includes a driver 601, an
elongated housing 602, an extending connector 604, a light source
and an extension module 605.
[0067] In FIG. 9, the light source is composed a first light part
606 and a second light part 607. In some other embodiments, the
light source may have one or more than three parts.
[0068] The driver 601 converts an external power source to a
driving current. For example, a power wire 607 guides an indoor
power source of 110V alternating current power to the driver 601.
The driver 601 includes a transformer, a rectifying circuit, filter
circuits or other components to convert the alternating current
power to a direct current power supplied to the light source and
the extension module.
[0069] In some embodiments, the extension module may carry a
battery to be charged in normal time and supplying power to the
light source when the external power is not available
abnormally.
[0070] The elongated housing has a lighting area 610, an extension
area 611 and a light opening 612.
[0071] The extending connector has a holder 613 and an electrode
614 connecting to the driver 601. For example, the holder 613 may
include a box for inserting the extension module. The electrode 614
is disposed inside the box so that when the extension module is
inserted, the extension module is electrically connected to the
driver 601 via the electrode 614.
[0072] The holder 613 is placed in the extending area 611 of the
elongated housing 602.
[0073] The light source is attached to the lighting area 610 for
generating a first light 616 escaping from the light opening
612.
[0074] The extension module 605 is attached to the holder 613 of
the extending connector to electrically connect to the driver 601
via the electrode 614.
[0075] In some embodiments, the extension module is detachable to
be replaced with another extension module. For example, users may
buy several extension modules with the same housing but with
different functions to be inserted into the holder 613 of the
extending connector 604. A first extension module may be a speaker
and a second extension module may be a wireless module to provide
wireless connectivity to the driver 601.
[0076] The extension module may be a camera module, a sensor
module, a Wi-Fi hotspot device or other function modules.
[0077] In some embodiments, the holder has a sliding track 621 for
inserting the extension module 605 from the direction of the light
opening 612, e.g. the bottom side of the elongated housing 602.
[0078] In some embodiments, the elongated housing 602 has two
lateral covers 623, 624 disposed on opposite sides of the elongated
housing 602.
[0079] A power wire 608 is connected to one of the lateral cover
for transmitting the external power to the driver 601.
[0080] In some embodiments, the elongated housing has two lateral
covers disposed on opposite sides of the elongated housing.
[0081] A light device connector 625 is disposed on one of the
lateral cover to connect to another lighting apparatus 626 for
routing electricity to said another lighting apparatus 626.
[0082] Said another lighting apparatus may have the same structure
as the lighting apparatus. In some usage examples, the two lighting
apparatuses may be the same but are installed with different
extension modules, e.g. one for a camera and another for a spot
light.
[0083] In some embodiments, the lighting apparatus may also include
a rotation button 631 and a manual switch 632.
[0084] The rotation button and the manual switch are electrically
connected to the driver.
[0085] The rotation button is used for perform a continuous
operation for setting a continuous parameter continuously to
operate the driver.
[0086] Specifically, the continuous operation refers to a
continuous parameter range. For example, a light intensity from 200
intensity units to 1000 intensity units is a parameter range. When
the light intensity is selected by rotating the rotation button,
the value may be selected like 250.002323 or 250.21235, which falls
in the range but has unlimited options, which is called
continuous.
[0087] In contrast, the manual switch provides a limited set of
options to be selected, which is called discrete options.
[0088] The manual switch provides multiple discrete options for a
user to select one of the multiple discrete options to operate the
driver.
[0089] The manual switch and the rotation button may be used for
controlling the same type of parameters, e.g. intensity or
different types of parameters, e.g. the rotation button for
intensity adjustment while the manual switch is used for indicating
a required color temperature. The manual switch may be configured
to co-work with the rotation button. For example, the manual switch
determines a parameter type and the rotation button determines a
specific value of the parameter type.
[0090] In FIG. 10, the lighting apparatus 671 is connected to a
series of other lighting apparatuses 672, 673, 674.
[0091] The lighting apparatus and the series of other lighting
apparatuses are configured to receive a wall switch command from a
wall switch 675 to adjust a color temperature at the same time. The
control signal may be transmitted to the lighting apparatus 671
first, and the lighting apparatus 671 routes or translates the
control signal to supply to other lighting apparatuses 672, 673,
674.
[0092] In some embodiments, the lighting apparatus is connected to
another lighting apparatus.
[0093] The light source of the lighting apparatus has a first type
of light modules and a second type of light modules. For example,
in FIG. 9, the first light part has a first type of light modules
631 and a second type of light modules 632. Specifically, the first
type of light modules 631 may emit light of a first color
temperature and the second type of light modules 632 may emit light
of a second color temperature.
[0094] Said another lighting apparatus has the first type of light
modules and the second type of light modules. Said another lighting
apparatus may have the same structure as the lighting apparatus
illustrated and explained above in FIG. 9.
[0095] The first type of light modules and the second type of the
light modules of the lighting apparatus and said another lighting
apparatus are alternatively turned on periodically to keep a
portion of the first type of light modules and the second type of
light modules of the lighting apparatus and said another lighting
apparatus to rest to control an operation temperature of the
lighting apparatus.
[0096] For example, if two lighting apparatuses are placed
together, and the two lighting apparatuses have the same
structures. To mix a required color temperature, in a first time
period, the first set of light modules of a first lighting
apparatus is turned on to accompany the second set of light modules
of a second lighting apparatus. In a second time period, the first
set of light modules of the first lighting apparatus is turned on.
The second type of light modules are turned on in the first
lighting apparatus to accompany the first type of light modules in
the second lighting apparatus to mix the required color
temperature.
[0097] In other words, some portion of light modules are rest even
the required color temperature is continuously provided. Such
design increase life span of the overall light devices and provide
a nice heat dissipation scheme.
[0098] In some embodiments, the light source includes a first light
part and a second light part.
[0099] The first light part and the second light part are disposed
on two opposite sides of the extension module, as illustrated in
FIG. 9.
[0100] In FIG. 11, the extension module includes an air filter by
guiding an air through a filter 653 of the extension module.
[0101] In some embodiments, the extension module includes an
ultra-violet light module 654 for sanitizing. The ultra-violet
module emits an ultra-violet light to kill undesired objects. Some
ultra-violet light does not cause harm to human and may be placed
outside while some other ultra-violet light may cause danger to
human and is therefore disposed in a concealed space for sanitizing
air flowing by.
[0102] In some embodiments, the extension module has a motion
sensor 656 to turn off the ultra-violet light module when a person
is detected.
[0103] In some embodiments, the extension module receives a timer
command to turn on the ultra-violet light module after a
predetermined time period. For example, a timer 655 is used to
determine a timing to activate the sanitizing, e.g. when people
leave the store or home and the sanitizing is started one hour
later after the setting.
[0104] In some embodiments, the lighting apparatus may also include
a fan 657 for creating an air 652 flowing by the ultra-violet light
module 654.
[0105] In some embodiments, the extension module is a speaker for
generating a sound.
[0106] In some embodiments, the light source is detachable from the
elongated housing.
[0107] In some embodiments, the extension module is a spot light
module for emitting a second light.
[0108] Please see FIG. 12, which shows an example of configuration.
The second light 631 is surrounded by the first light 632, and the
second light 631 has a larger intensity than the first light
632.
[0109] In FIG. 9, the driver sends a status signal to an external
device 626 when the driver detects insertion of the spot light
module to change a control interface for controlling the lighting
apparatus via a wireless interface.
[0110] For example, the external device is a remote control or a
mobile phone installed with a corresponding App. The corresponding
App adjusts a control interface by determining the status signal
indicating the type of the extension module.
[0111] For example, when the extension module is a speaker, the
interface is different from the case which the extension module is
a spot light module.
[0112] In some embodiments, a pulling string 628 is selectively
attached to a string connector 641 connected to a string switch 642
of the driver 601 to control the light source by pulling the
pulling string 628.
[0113] In some embodiments, a button 629 is disposed at an end of
the pulling string 628.
[0114] The button 629 is operated to send an instruction to the
driver 601 in addition to the pulling of the pulling string 628.
For example, the button 629 may switch an operation mode, control
the extension module or change a color temperature of the light
source.
[0115] Please refer to FIG. 1. In FIG. 1, a lighting apparatus
embodiment has a top cover 3. In addition to the top cover 3, the
elongated housing 1 has a connector 6 for connecting to other
lighting apparatuses.
[0116] There is a switch 7 placed in an escaping groove 9. The hook
8 is used for hanging the lighting apparatus on a bracket.
[0117] Please refer to FIG. 2, which illustrates a side view of the
example in FIG. 1. The same reference numerals among drawings refer
to the same components and are not repeated for brevity.
[0118] In FIG. 2, the light source 12 emits light passing through a
light passing cover 4. The hinge axial 10 is used for attaching the
hook 8. The switch 7 is used for operating the lighting
apparatus.
[0119] There is a magnetic unit 5 for attaching an inserted
extension module. A battery 2 may be added for emergency
lighting.
[0120] FIG. 3 shows another view of the example in FIG. 2 and FIG.
1.
